To all whom it may concern:

Be it known that I, THOMAS B. SANsBunY, a citizen of the United States, residing at -Daleville,in the county of Dale and State of Alabama-have invented new and useful Improvements in Carbon-Preventing Means for Internal-Combustion Engines, of which the following is a specification.

My present invention has for its object the provision of means adapted to be used to advantage in conjunction with a Ford or other internal combustion motor, with a view to utilizing commingled water and coal oil or other appropriate fluid to advantage in preventing the formation of carbon in the cylinders of the motor.

To the attainment of the foregoing the in vention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figure 1 is a general view illustrating my novel apparatus as properly arranged with respect .to a Ford motor.

F igure 2 is an enlarged detail view of the pump comprised in the apparatus.

Figures 3 and 4 are enlarged sections showing the pump and timer.

Figure 5 is an enlarged view showing one of the valve casings and the parts carried by said casing.

Similar numerals of reference designate corresponding parts in all of the views of the drawings. I In furtherance of my invention I employ an appropriately supported tank 1 adapted to contain coal oil and water or other appropriate fiuid for the purpose stated, and on each cylinder 2 of the motor and in cornmunication with the explosion chamber thereof ll employ an upstanding casing 3. The said casings 3 are identical in construction and therefore a detailed description of the one shown in Figure 5, and the ap: purtenances of said casing will suffice to impart a definite understanding of all. At its upper end the casing 3 referred to is pro- .vided with an escape or vent cock 4E. Said casing is also provided with a supplemental, horizontally d sposed casing 5 to which is connected a pipe 6 to supply coal oil and water or other fluid, communication between the casing 5 and the casing 3 being controlled by a regulating valve 7. In the casing 3, which is preferably in sections as shown, are arranged two valves 8 subject to the action of springs 9 and spaced apart for an important purpose hereinafter set forth.

Also in furtherance of my invention I employ a gear 10 on" the cam shaft 11 of the motor, and with the said gear I connect an upright shaft 12 for transmitting motion to the pump and timer of my improvement. The said shaft 12- is disposed in a housing 13, and the said housing is preferably utilized as a support for the pump and the timer. On the shaft 12 is fixed a cam 14 by which are moved outwardly the four pistons 15 of the pump, the said .pistons 15 1 being maintained against the cam and being moved inwardly through the medium of springs 16, one to each piston. The cylinders 17in which the pistons 15 work are each provided with a non-return valve 18, said valve being located in the eduction passage of the cylinder which passage is connected by a pipe 18 with the receiving end of a casing 5. Each cylinder 17 is connected by passages 19 and 20 in which are nonreturn valves 521 and 22* respectively, with chamebr 23*. The said chambers 23* are in full communication with each other, and connected with one of the chambers is a conduit arm 248 between which and the tank 1 is a pipe 25*. The before mentioned pipes 6 communicate with and extend from the pipe 25*.

At 20 is a timer which may be of the construction illustrated or of any other appropriate construction, the rotary portion of the timer being carried on the shaft 12.

By particular reference to Figure 1 it will be apparent that the entrance from each valve casing 3 into the explosion chamber of the cylinder carrying said valve casing 3 is directly over the piston; also, that by virtue of the spaced duplex valves 8 1n the casing 3, the casing is adapted to hold a certain amount of fiuid at all times so that when a stroke is made by the pump, the

amount of fluid that is permitted to pass the adjustable valve 7 will displace the amount between the two valves 8 and the said amount will be forced by the pump into the explosion chamber of the cylinder.

The timer 20 serves to assure the injection of fluid into each cylinder at the proper time with respect to the working of the piston in said cylinder, and it will be noted that the timer 20 is located in an elevated position out of the way of water and oil from the motor, and that the timer comprises a conventional roller and commutator cover.

Incident to the operation of my improvement each piston 15 operates under normal conditions to draw the fluid mixture from a chamber 23 and force the same past a valve 18 to a casing 3. When, however, the pressure in the engine cylinder prevents unseating of the valve 18, the piston 15 will force the fluid mixture past the valve 22 and back into one of the chambers 23*. The suction created in the casings 5 incident to the operation of the improvement operates to draw portions of the fluid mixture from the pipes 6 into the casings 5 where such ortions of fluid mixture will be commingle with that forced from the pump.

Experience has demonstrated that water and coal oil form a mixture which when properly handled is an effective means for preventing the formation of carbon in internal combustion motors, and experience has also demonstrated that when a proper quantity of the mixture is put into an internal combustion motor cylinder at the right time, the mixture will serve the purpose ascribed to it without in any degree affecting the working of the'engine.

It will be gathered from the foregoing that the conduit 25 is provided with a cut off valve 22. In order to maintain the interior of the portion of the apparatus containing the chambers 28 in a warm or heated state I provide the drum 13 Figures 1 and 3, which is arranged below and in close proximity to the said chambered portion. The said drum 13 is provided in its top wall with eduction apertures13 in communication with the atmosphere and for the escape of heated air. Through the medium of a conduit 12 the drum 13 is connected with a jacket 11 about a portion of the exhaust manifold of theengine; the said jacket 11' having induction means for atmospheric air and being designed to confine the air in proximity to the manifold portion so that the air will be heated precedent to the conduct of the same through the conduit 12 to the drum 13 for the purpose stated.

Having described my invention, What I claim and desire to secure by-Letters-Patent, 1s:

1. The combination with the cylinders of an internal combustion motor, of valve casings communicating with the explosion chambers of the cylinders and extending upwardly therefrom, spaced valves in each of said casings, a regulating valve carried by each of said casings, a reservoir, a pump and a timer therefor operable by the crank shaft of the motor, a conduit intermediate of the reservoir and the pump, and means connecting the pump and the regulating valves of the several valve casings.
